On the Use of Gabor Filters in Designing Steganographic Distortion

With recent advances in steganography the most integral part left to steganographer
is designing the distortion function. In this paper we propose a new adaptive scheme
in defining the distortion function using Gabor filters in spatial domain. Compared
to other embedding algorithms, our proposed method, using fine directional grid of
Gabor filters, put higher emphasis on cluttered and textured areas in the image than
on the edges. Our test results using the state-of-the-art steganalysis algorithms
show the superiority of our approach.
